TYPE-WRITER;

To all whom it may concern;

Be it known that I, GnA'RLn's Sco'r'r \VAT- sox, a subject of. the King of Great-Britain and Ireland, residing at Newcastleeupon- Tyne, in the county of Northumberland',

England, have invented Improvements in Type-Vi'riters, of which the following is a specification.

- This invention relates to improvements in ty e-writer's of the kind wherein, by means of ey-actuated punchesthere are roduced, upon a sheet of paper or like suita le material, raised or embossed impressions forming characters that are legible by the blind.

In a typewriter according to this invention there is secured upon a base referably of rectangular-form a pair of'para lel bars that are furnished with mdentations that correspond with the spacing of successive lines of r-carrying 'bar that is typed matter; a' pa to said rails, thatcan arranged transverse y be moved along the same, purpose-of regulating thelspacing of success'ivc lines, is furnishedwith projections that are adapted to an age with the indentations in the rails, a bri ge extending transversel in relation tothe operator and to said para lel bars, a carriage mounted on said bridge and adapted to traverse the same, a s ringor recesses to receive the points of thepunches wl. en the same are actuated by the keys.

The' accompanying drawings illustrate tvpewriting apparatus in accordance with this invention; wherein Figurel is a plan of the apparatus viewed from above; Fig. 2 is'a front elevation, keys being removed; Figs. 3 and 4 are side elevations viewed respectivelyfmm the left and right; Fig. 5 is a detail view, partly in elevation andpartly in section corresponding to the'line A-A in Fig. Fig. 6 is a lon 1-: tudinal sectional view-of a portion of t e mechanism, illustrating t e arrangement of the punches; Fig. 7 is a central transverse section through the carriage; F1g, 8 1s a rear Specification of Letters Patent.

e evation of the escapement mechanism; and Fig. 9 is a side elevation of the same, viewed from the right. r V

The carriage 1 is mounted upon and adapted to traverse a bridge composed of front and rear bars 3 and4respectively that arose-cured,

as by screws, to standards 5 and 6 attached to the .baseof the apparatus. This base,-

which consists of an open rectangular frame, preferably of hard wood, comprising sides 7-- and- 8 respectively paral lel to and transvi'arsc to the bridge, has secured to each of its sides 8 a bar9 furnished with indentations 10'th'at are successively arranged at a distance apart corresponding with the space desired between successive typed lines. The paper carrier '11, .to which for. holding the paper, there is attached a clip 12 furnished with a tight'en'ing screw '13 is supported upon the bars 9, by'

terminal pieces 14 of H-section,wl1ose' rooves I 15 are adapted to engage the rails, w ile the pair of pro ections .16 in each such groove are adapted to enter a pair of adjacent indentations 10. The sides of the terminal pieces 14 are so situated in relation to one another that when the paperand its carrier are turned over, the lines of typing on one side fall bet-wcen'those on the other side. For the purpose of allowing the paper to be laterally adjusted, the clip 12 is arranged to slide on the carrier 11 withiniimits determined by the slot 17 through whichthe screw 13 passes; while to prevent the clip from being easily disturbed there is rovided on each side of the carrier a spring rictional device 18. The unches 19 which may conveniently be six in number, as shown, are arranged within a central aperture 20 in the carriage 1; and their lower ends pass through suitable 'uiding apertures in a pair of guide plates 21 and 22 attached to downwardly projecting studs 23 upon the carriage, while their upper ends are flexibly connected to the inner arms rojections 16 on opposite 24 of levers 25 that are fulcrumed at 26 upon 11 wardly projecting studs 27, and have t eir' outer arms connected by tensional springs 28 with the carriage, and by short rods 01.: 1il1k5 29 with the inner ends of the key levers 30 that terminate in the keys 3]. and upwardly from the carriage.

The platen 33 is secured to the standards 5 are fulcrumed on studs 32 projecting of detents 49 an I I I is in-its normal ppsition or is depressed under and 6 beneath the track of the lower. ends of the'punches 19, and has formed in it three. grooves 34 to receive the points of the punches, which are arranged in pairs above In some instances there may coves suitable ree platen.

the standard a these coves. .be su stituted forthe ccsses or depressions in t There is o'urnaled upon spring drum 35 to which is attached a tape 5 right and left hand groups, between which groups is a s acin key 40 that is attached to a bar 41 W- eb hes immediately below the key levers 30,- and is forme integrallywith' "isi'caused action of the s g drum 35 the arrange-" I that whenever the bar 41 is} depressed either directly by thespacing key go or securedto levers 42 pivoted at 43 to the carria e 1.-

To the bar, vlich, by the action szpring blades 44, is maintained in contact is the key levers 30,".there is attached escapement mechanism .whereb the carriage .1 to traverse-the bridge under the ment being suc- 40, or in consequence of the depression of one space corresponding .to -that occupied a or more keys 31'toJpri nt a characten'the escapement is thereby actuated "to admit of. the -movement of .the ;carriage throu h a typed character.

The esca e'ment mechanism corn rises a ratchet 48 ormed u on the under si e of the front bar 3 of 'the ridge, with-whichithere- 50, according as the bar"'41 the action of. e keys.
